i aolaims. (crew-193) This invention relates to an attachment for plows,the general object of the invention being to provide means forfacilitating the turning under of vegetable matter by the plowbyproviding a wing member adjustably connected with the I 18 Thisinvention also consists in certain other features ofconstr'uction and inthe combination and arrangement of the several parts to be hereinafterfully described; illustrated in the accompanying 'drawingsandspecifically pointed out inithe appended claims. fi

v In describing the invention in detail, reference will be had to theaccompanying drawings wherein like Characters denote like orcorrespo-nding parts throughout the several views, and in which: a

in use on a middle busterf plow and also combined with a disk coulter.

Figure 2 is a perspective view of the device shown in Figure 1.

- Figure 3 is atop plan view of Figure 1 and showing the coulterremoved.

Figure 4 is a top plan view showinga single wing type of device usedwith an ordinary plow. Figure 5 is a view of a bracket used withthedevice shown in Figure 4. I

Figure 6 is a'section on the line 6-6 of Figure 2. c

Figure 7 is a section on the line 1- of Figure 2.

depending connecting plates of the device are attached to the beam of aplow.

As shown in these drawings the device comstraight front ends 2 whichslope upwardly and contact each other and are detachably connectedtogether by bolts 3. Thesewings are in the form of flat bars and theyare divergently curved rearwardly as shown. Adjacent the rear ends thewings are connected by the brackets 4 to the lower ends of the posts 5which have their upper ends curving forwardly and intermediate theirends the posts are connected together by a brace 8, An upper clampingmember 9 is composed vof Another object of the invention is to provideFigure 1 is an elevation showing the invention Figure 8 is a top planview showing'how the prises a pair of wings I which have short and' twoparts which have their inner ends overlapping and connectedtogetherbythe bolts I0 and the outerends of the two parts are provided with slotsl I through whichthe posts pass. A shorter lower clamping member I2 isof substantially the same length as one of the sections of the memher 9and has a slot l3 in its outer end through whichapost passes and itsinner end is' provided with holes for receiving the bolts l0. These twomembers 9 and I2 act as clamping means for en-' gaging the. beam B of aplow so that they fasten the device to the beam'but in a manner to per-jmit the posts to move vertically through the slots II and I3 though thismovement can: be regulated by means of the cotter. pins I5 passingthrough desired ones of holes H5 in the top portions of the posts. Thetwo clamping members 9 and [2 are further'conr'iected together by a boltl8, see Figure 6, which passes through holes in the member 12 andonesection of member 9 immediately above it, said bolt also passingthrough a spacer ldlocated between the two parts.

A pair of depending plates 20 pivotally support the devicerrom the frontend of the beam and the parts 2 of the wings pass between these ,platesand are pivotally connected thereto by the bolt 2| and the spacer '22,these parts passing through any one of a plurality of holes 23 in theplates, the holesbeing arranged in a vertical row. The plates 20 areprovided with the holes 24 and theslots 25 for receiving fastening meansfor connecting them to the front end of the beam and if the beam istapered as shown in Figure 8, shims 26 can be placed between the sidesof the beam and the plates to make the plates parallel.

When the device is used on a middle buster or similar plow shown inFigures 1, 2 and 3 the double arrangement of wings and associated partsis used, but when the device is used with an ordinary plow such as shownin Figure 4 then one of the wings and one of the posts are removed andbut one section of the clamping plate 9 is used so that this section andthe section I2 clamp the beam of the single plow. Also a plate such asthat shown'at 30, in Figure 5 is fastened by the bolts 3 to the end 2 ofthe single wing usecl As shown in Figure 1 the slots 25 of the plates 7the front end of the beam and also through the shank of the clevis 33 ofthe beam.

From the foregoing it will be seen that this device is pivotallysupported from the front end of the beam for swinging movement in avertical plane and the posts or post support it for limited verticalmovement from an intermediate part of the beam so that the wingstructure can move upwardly or downwardly to a limited extent and saidwing structure should be arranged adjacent the ground level when theplow is'in the ground so that it will spread and flatten vegetation,such as vines and the like, so that the plow can readily plow themunder.

Of course, when a double type of plow is used both wings should be used,but when asingle type of plow such as shown in Figure 4 is used then oneof the wings is removed; Whenever desired a disk coulter such as shownat C in Figure 1 can be used and when so used it will travel in thespace between the two wings. Also as shown in this figure the majorportion of each wing is substantially horizontally arranged but slopesupwardly and forwardly at its front end.

. Where the vegetable growth is heavy then the wings can be presseddownwardly by means of the springs 35 which are attached at one end tothe member 9 and the other ends to the upper ends of the posts sothat'the springs will tend to move the posts downwardly and thus yieldinglypress the wings against the vines or plants. These springs can encirclethe posts or they may be arranged as shown inthe drawings'with eachspring having a hook at its lower end engaging a notch formed in a wallof a slot 1 i and with its upper end engaging a part of the cotter pin[5 so that the spring will be adjusted as the cotter pin is adjusted.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. An attachment for a plow comprising a wing member, means forpivotally connecting the wing member to the front end of the beam of theplow, said wing member having its front end sloping downwardly andrearwardly and the rest of the member arrangedsubstantially,horizontally and curving outwardly and tending to spreadand flatten vegetation in front of the plow and means for supporting thewing member from an intermediate part of the beam for vertical movement.

. 2. A plow attachment of the class described comprising a pair of wingmembers each including an upwardly extending front part and outwardlycurved rear part substantially horizontally arranged, brackets dependingfrom the beam of a plow and to which the front ends of the wings arepivoted, posts rising from the intermediate portionsof the wings,clamping plates the front ends of said partsto the bracket, posts 1rising from the rear portions of the wings, a brace member connectingthe posts together, upper and lower clamping plates adapted to beclamped to a beam, the upper plate being formed of two sections, saidclamping plates having slots in their outer' ends for the passage of theposts and means for limiting downward movement of the posts through theslots.
